When NASA one day sends humans to Mars, the journey could take six to nine months each way. But there's a highly-experimental device being developed that could help get us there in less than half that time — if it really works.

Under the icy water surrounding Earth's poles, there's a hidden world of dramatic landscapes — ancient canyons, craters, hills and fields. A group of scientists has compiled a new atlas of some of those formations and released images from the collection on Tuesday (April 25) at the annual meeting of the European Geosciences Union in Vienna.

Developed at the Children's Hospital of Philadelphia, an artificial womb kept a lamb fetus alive for four weeks. By using synthetic amniotic fluid and a pumpless oxygenator to deliver nutrients, the lambs in the study were shown to have normal lung and brain development. It's a potential new step in saving the lives of thousands of babies born very prematurely each year.

In 1965, President Lyndon Johnson signed the High Speed Ground Transportation Act into law. It was supposed to usher in a new era of high speed bullet trains connecting every city in the U.S. But that never happened. Why did our plans for high speed train travel never get on rails?

Inspired by the space race and landing on the Moon, years of research in the 1970s went into creating colonies that could transport large populations of humans into the stars. But that never happened. What went wrong with our plans to colonize the universe?

The world’s bees are in big trouble — even more than you might have realized. Their extinction would affect the food supply, cosmetics, crops, and climate change, but scientists are hopeful they can save these important insects.

Long after the last SoundCloud downloads have succumbed to the second law of thermodynamics, and the final music CD has been digested by polycarbonate-eating bacteria, Chuck Berry will still be rocking.

In the last 50 years, there have been at least 44 oil spills in U.S. waters. Innovations to the response process are ever more imperative to prevent similar damage to the ocean like the kind inflicted by Deepwater Horizon.

A new landmass discovered beneath a tiny island off the coast of Madagascar is a reminder that Earth’s continents are always on the move, continuously drifting together before breaking apart in a never-ending cycle that will one day lead to another Pangaea.

Humans worldwide produce between 35 and 40 billion metric tons of carbon air emissions each year. Some of the world's top minds are creating ways to transform that pollution into valuable, revenue-generating products.
